Description
Much of the current push in quantum technologies relies on one assumption: Quantum mechanics is valid for complex and macroscopic systems. Although recent experiments have demonstrated the entanglement of mesoscopic objects, there are some aspects of quantum mechanics that are yet to be tested beyond the few-atoms level. We observed for the first time the famous Einstein-Podolsky-Rosen paradox with two spatially separated, massive many-particle systems – two atomic Bose-Einstein condensates. Our results show that the conflict between quantum mechanics and the classical understanding of reality and locality does not disappear when the system size is increased to more than 1000 massive particles.
